Definitions
- the invention relates to a process for the agglomeration of finely divided rubber latices by adding an amphiphilic block copolymer.
- agglomeration is understood to mean the gathering together of latex particles to form spherical piles, the primary particles being partially or completely fused to one another.
- Coarse rubber particles can be made by direct emulsion polymerization, such as. B. is described in DE-A 1 247 665 and 1 269 360.
- these direct polymerization processes have the disadvantage of long polymerization times, usually several days, until the desired particle diameter is achieved with almost complete conversion.
- high polymerization temperatures are often used. This leads to the formation of hard-to-remove Diels-Alder adducts such as vinylcyclohexene, which persist in the latex particles.
- the coarse rubber particles can be generated by the agglomeration of finely divided latices.
- Finely divided latices should be understood to mean those with an average particle diameter (DVN) of 40 to 250 nm.
- VN average particle diameter
- the finer the latex the shorter the polymerization time.
- Agglomeration can be triggered by physical and chemical processes. The formation of unwanted coagulate is very difficult, i.e. avoid very large agglomerates (several ⁇ m to mm in size) that separate from the dispersion and are not redispersible. Such coarse fractions also reduce the gloss and impair the mechanical and surface properties of the plastics made from the latex, e.g. B. ABS.
- a chemical method for enlarging rubber latices is described in DE-A 2 606 715.
- the rubber latex is acetic anhydride added.
- the acetic acid released by hydrolysis neutralizes the carboxylate emulsifier and destabilizes the latex until the rubber particles agglomerate.
- the method can only be used with weakly acidic emulsifiers, such as. B. salts of organic acids.
- Latices that are stabilized with highly effective sulfonate or sulfate emulsifiers cannot be agglomerated with this method.
- the process has the disadvantage that the agglomerating latex, because of its extreme shear sensitivity, must not be stirred during the agglomeration phase and must be stabilized with acid-stable emulsifiers or alkali after the agglomeration. This creates a high level of wastewater pollution.
- the possibility of continuous agglomeration is ruled out.
- a continuous agglomeration process has the great advantage of being able to intervene in a controlling and regulating manner in the event of disturbances in the agglomeration or deviations from the desired average agglomerate size.
- the agglomeration is triggered by oxidized polyethylene oxide.
- the agglomerated latices have a very broad particle size distribution, which is disadvantageous, for example, in ABS production.
- the latices obtained using this method are only of limited stability during further processing steps.
- unoxidized polyethylene oxide (PEO) is used, ammonium salts must be added (US Pat. No. 3,288,741), which leads to a higher waste water pollution.
- EP-A 330 865 branched polyethylene oxide is used before or during the emulsion polymerization. Again, significant amounts of alkali or ammonium salts have to be used.
- DE-A 2 427 960 uses a second latex containing carboxyl or amide groups as an agglomerating agent.
- the agglomerated latices have a very broad particle size distribution and contain a considerable proportion of non-agglomerated, finely divided rubber particles.
- a latex is used as the agglomerating agent which is stabilized with a PEO-PS-PEO triblock copolymer, narrow particle size distributions are achieved without the formation of coagulum according to the teaching of EP-A 249 554.
- the production of the latex used as an agglomerating agent presents difficulties. Both methods are based on the complex production of a second latex, which causes additional costs.
- the object of the invention is to develop an environmentally friendly and cost-effective method by which fine-particle rubber latices can be agglomerated quickly and on a large scale and in an economically feasible manner to form coarsely coarse rubber latices.
- amphiphilic block copolymers which have certain minimum molecular weights for the hydrophilic and hydrophobic blocks, for the agglomeration.

- Example 1 Example 1
- Example 19 Analogously to Example 1, the latices listed in Table III, column 2 were experimentally agglomerated with the agglomerating agents specified in Table III, column 8 and the agglomerating agent concentration listed in column 10. The properties of the agglomerate latices are shown in columns 12 to 14. Typical dark field micrographs are shown for the agglomerated latex of Example 2 in FIG. 3. Example of continuous agglomeration: Example 19
- 60 L of latex 1 are mixed continuously with 12 L of a 1% solution of compound II per hour in a static mixer (6 mm in diameter, 12 mm in length).
- the agglomerated latex is collected in a stirred template. No coagulum formation is found.
- An agglomerated latex with an average particle size of 320 nm and a solids content of 32.9% by weight is obtained.
- amphiphilic agglomerating agent is not according to the invention, see comparative examples V9 to V12, then practically no agglomeration of the latex occurs: the block compounds VI, IX, X and I prove to be ineffective, they do not have the appropriate structure. Analogously, the “agglomeraf” latices have only slightly larger average diameters. Coagulation does not occur when VI, IX, X and I are added.
- an agglomerating agent here compound II: Borchigen SN 95
- K-oleate (example 13)
- resin soap dresinate (example 14)
- K-palmitate (example 15)
- K-laurate (examples 16 and 19)
- tallow fatty acid Kali TU (Example 17) produced primary latices of comparable particle sizes, so much coagulum (10 to 60%) can arise.
- Such massive coagulum formation comes with those with dimer soaps manufactured latices.
- the latices from Examples 13 to 17, after filtering off or sieving off the coarse coagulum show a practically unchanged particle size compared to the primary latices.
- the agglomeration conditions must be adjusted more closely so that the formation of coagulum can be minimized.
- the formation of coagulum can be reduced by:
- Coagulate are formed than at 20 ° C, see. Examples 20 and 21), but not above 70 ° C an adaptation of the structure of the agglomerating agent (e.g. less coagulum can be formed if the hydrophobic block of the amphiphiles
- Dilution of the starting latex and / or the addition of additional emulsifier can lead to the formation of smaller agglomerated particles; in such cases the particle size can be increased by slightly increasing the salt concentration (eg addition of 0.5% by weight Na 2 SO 4 , see Examples 26 and 28) can be enlarged without the formation of larger amounts of coagulum.
- polybutadiene latices can be agglomerated with the process according to the invention, but rubber latices in general are suitable for agglomeration according to this process, as examples 29 to 35 based on poly (n-butyl acrylate) latices show.
- Examples 32 to 35 also show that amphiphilic copolymers with hydrophilic segments which have a structure not based on ethylene oxide are also suitable for agglomeration.
- an agglomerating agent such as VI
- VI agglomerating agent not according to the invention
